In generating a noise pulse, the flash-bang projectile provides a housing that includes a gas chamber that entraps air.

Abstract: A high precision electro-mechanical fuze mechanism for a munition such as a hand grenade. The fuze mechanism includes an electromagnetic signal generator having an armature, a permanent magnet, a coil and a magnetic impulse generator (MIG) member. The armature is preloaded during assembly through the use of a spring. Releasing an actuating lever of the grenade allows the armature to begin spinning and to dissipate the energy stored by the spring. This causes a current to be electromagnetically generated in the coil, which is transmitted to an electronic control circuit in the fuze mechanism. The electronic control circuit implements two time delays from two separate timers which each must time out before the control circuit can send an electric firing signal to an electric detonator. Movement of the armature also causes a simultaneous movement of a rotor, which moves a stab detonator into a position closely adjacent the electric detonator.

Overlying the piston is a primer and a piezoelectric device and primer that, when impacted by a striker produces pressurized gas for driving the piston and electricity for an electronic delay circuit. The piston moves the operating rod to bring the toggle body and detonator into alignment with the transfer lead and booster for detonation.

Abstract: A dipole magnet is placed in a sabot of an explosive projectile. The magnet is arranged and configured within the interior surface of the sabot--such that when the sabot is placed over the casing of the projectile, the majority of the magnetic flux tends to take a path through the projectile casing and between two sensing coils located within the fuze and within the projectile. The first sensing coil forms a larger circle which encompasses the aft end or outer diameter of the projectile which is made up of ferrous materials. The second sensing coil forms a smaller concentric circle (relative to the first sensing coil) and is situated inside the inner diameter of the after end of the projectile, thus encompassing no ferrous metal. The majority of the flux from the magnet enters the ferrous projectile casing, travels through the casing, and exits primarily between the two coils on a continuous path back to the magnet.

A fixedly disposed primary coil which receives an ignition signal is provided at the combustion chamber while a secondary coil is arranged in each propellant charge member, this secondary coil being connected to a resistor initiating the ignition system. The magnetic field, changing with time, which is produced by the primary coil penetrates the combustion chamber and induces a current in the secondary coils of each propellant charge member at the same time so that the ignition systems of all propellant charge members are simultaneously activated and ignite all propellant charges at once. On account of the simultaneous ignition of the propellant charge members, rapid firing sequences can be attained.

Abstract: A compact transmitting device located in an exploding projectile transmits an RF pulse upon explosion of the projectile. Receipt of the RF pulse, through triangulation or equivalent techniques, identifies the burst point of the projectile. The transmitting device comprises a magnetic circuit that includes a permanent magnet, a ferromagnetic core having an air gap some distance from the permanent magnet, and a coil in the air gap. Stored energy in the permanent magnet is converted into a high power electrical pulse when the permanent magnet is destroyed. Prior to destruction of the magnet, a constant high magnetic flux exists in the air gap, but induces no current in the coil because it is a constant flux. Upon destruction of the permanent magnet, the magnetic flux changes rapidly, causing a high power electrical pulse to be generated.

Abstract: A well perforator system and method employs an electromagnetic wave frequency receiver, one for each of at least two gun intervals, that receives a transmitted signal conveyed through well tubing from the earth's surface. The signal is converted to an electrical pulse which detonates a blasting cap and fires the gun perforators. Each gun interval is a separate system with different activating frequencies and each is separately activated to assure that all the intervals are fired. A timer may be used to activate the electromagnetic wave receiver after the gun is in the well to prevent accidental surface firing of the guns from stray sources of electromagnetic waves. Once in the well, only the transmitted pulses are able to detonate the guns. Once the last interval is fired, a wave frequency-activated gun above the uppermost gun interval is detonated with circulation shots to penetrate only the tubing. This creates an instant, intense pressure drop across the perforations to help in cleanup.

Abstract: In the method of increasing the detonation energy in an electromagnetic fuze system of a low-acceleration projectile a detonator generator which is held in an inactive or rest position by an elastic force, is accelerated along a predetermined travel path in the rear portion of a housing at the onset of the firing acceleration. The detonator generator is accelerated such that the detonator generator impacts upon an impact body which is provided with a central bore. As a result, a reaction member of the detonator generator inactivates its mechanical safety device and is accelerated, thus providing the detonation energy. In the retarding phase the detonator generator is returned into its original position by means of the elastic force and thus is ready for detonation. In comparison to known methods and apparatus there can thus be dispensed with an external power supply, whereby safety is increased with respect to maintenance, tests and firing.
